An oncogene is a gene that has the potential to cause cancer. In tumor cells, these genes are often mutated, or expressed at high levels. Most normal cells will undergo a programmed form of rapid cell death (apoptosis) when critical functions are altered and malfunctioning. Activated oncogenes can cause those cells designated for apoptosis to survive and proliferate inste… WebThings like smoking, not exercising enough, drugs, your diet, and environmental chemicals or radiation can result in chemical changes to DNA outside of genes that can result in …
